MI combat rail barrel nut wrench

I got a used MI handguard…. Do I really need a specific wrench, or does something general overlap?

You can get the MI wrench for 10 bucks if you don't have a spanner wrench that fits it.

A castle nut wrench might do it….https://uploads.tapatalk-cdn.com/202...3dc7e9ca35.jpg
That’s the Magpul wrench on top of the MI…..if they’re not the same pattern, it’s really close.
